My first experience with a go-go girl, or any thai working girl for that matter, was during my first visit to Pattaya. At the time, I had no clue about the scene and wasn't planning on taking anyone back with me, hell, I didn't realize I could at the time! I was staying at a high end hotel during that time. Well, it was also my first experience with paying a joiner fee.
Took the girl back to the hotel, scared sh!tless about being seen by others with a girl in tow, waltz into the hotel with the girl and smiling to the 2 security guards standing near the entrance to the elevator. Was stopped and directed us to the receptionist desk. Got me worrying. That was when they had me pay the joiner fee and after which, allowed my guess to come up the elevator with me.
If it's true what this hotel is doing with their guests, it's complete bullsh!t and unfair to their guests. The appropriate actions from the hotel should be to approach those they believe are taking guests back up to the room and having them register their guests and paying the joiner fee as it happens.
